I recently stayed at Pantanida's place for 1 whole month. I had a great experience and was very happy with the room and service provided.
The condo is extremely close to an MRT Station which allows you to travel quite easily around Bangkok. Close to the room are a lot of local Thai food restaurants and stalls which sell cheap and tasty Thai food.
The room was clean and tidy and I enjoyed sleeping there for 1 whole month.
Pantanida and her sister are very kind and welcoming and were great hosts.
I highly recommend staying at this condo if you are travelling to Bangkok. You will not regret it.
